Which of the following contributes to the specificity of binding between DNA and a repressor protein?

Question

Quizplus · Accepted Answer

The specificity of binding between DNA and a repressor protein is contributed by both the specificity of the interaction between bases and amino acids, as well as the ability of DNA to assume certain shapes. The interaction between specific amino acid residues in the repressor protein and specific bases in the DNA is crucial for the specificity of binding, but the ability of the DNA molecule to assume particular shapes is also important for the creation of a specific binding site. Therefore, the best choice is E, which combines both of these factors.
